I started using Newton in early March and believe I need to fix my profiles.

When I started I entered my body weight with riding gear on and weighed my bike with water bottles and entered that. So my total weight was 205.

Then a few weeks later I did an FTP test and when it asked my weight I entered it and then did the FTP test. Which sucked by the way. I had lost a few lbs from initial set up by that point.

After my FTP test it adjusted my Rider Weight to what I entered on my FTP test, but added the difference to Bike + Other weight so total weight remained the same at 205. (I didn't notice this at the time).

I did another FTP today, entered my weight prior and had lost a few more lbs, and when I uploaded my ride it adjusted my rider weight, added lbs to Bike + other weight so total weight remained the same at 205.

Hopefully that makes sense.

My two main questions are:

1. What is best way to update my profile?

2. How do I adjust my FTP since I"m guessing it's high since my total weight isn't likely 205 any more.

It also looks like you did your 3/20 and 4/24 FTP tests on the same stretch of road; that's good, too. It's also good that it is on an uphill; that provides a constant amount of force that you have to overcome during your test.

Your 3/20 ride showed a speed of 10.8 mph and a 20 min watts of 247.9W

Yor 4/24 ride showed a speed of 11.9 mph and a 20 min watts of 264.5W. So, you definitely did better. Furthermore, your watts output on your 4/24 ride had less variance towards the end of the test, so you're improving your pedaling skills too.

After the ride you can check the effect of weight on your result by using the "Analyze/Analyze Newton Settings..." command, then adjust the weight.

A reduction of 1 pound in weight reduces your 20 min watts by only 1W. So, the effect is not as big as you might think...

In Edit/Edit Profiles you can permanently change your weight. Change weight in both the settings on the Basic Tab and Advanced Tab, and change your FTP in the Basic Tab. Send the profile to your Newton. You'll be all set.
